• Specications obtained at sea level using water as the recirculating uid, at a 20°C process
setpoint, 25°C ambient condition, at nominal operating voltage, on chillers with P 2 pumps with
no back pressure (P 3 pumps set to 10 gpm for ThermoFlex15000 to 24000). Other uids, uid
temperatures, ambient temperatures, altitude, operating voltages or pumps will affect performance.
See Section 3.
• Chillers require the use of 50/50 EG/water or 50/50 PG/water below 10°C process temperature to
prevent freezing/glazing of the plate exchanger.
• Thermo Fisher Scientic reserves the right to change specications without notice.

• Pump curves are nominal values. Pressure values for centrifugal pumps are differential pressures
between the inlet and the outlet of the chiller.
• Pump performance results were obtained with no restrictions on the return to the system or with
any options installed. For example, utilizing the DI option will result in a 0.5 gpm ow reduction .

• Pump curves are nominal values. Pressure values for centrifugal and turbine pumps are differential

• Pump performance results were obtained with no restrictions on the return to the system or with
